From 78ecf091aa592a9e160ebbbfa5873c2bb2e2d0f8 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 17 Jun 2009 12:29:55 +0200 Subject: [PATCH] ttm: Return -ERESTART when a signal interrupts bo eviction. A bug caused the ttm code to just terminate the wait when a signal was received while waiting for the GPU to release a buffer object that was to be evicted.
